Patent DE-3303624-C1 (DE)
Title: Plug-in connectors for optical fibres having electrical interfaces
Inventor: ISERT HANS DR-ING
IPC: G02B6/38
Filed: 1983-02-03
Granted: 1984-07-26
Abstract: In the embodiment according to the invention of plug-in connectors for optical fibres having electrical interfaces, the plug-in contacts are rigidly attached to the optical fibre. The plug-in contacts are connected to a plug housing in which there is located in each case a hybrid circuit embodied on a substrate and fitted with semiconductor components. This hybrid circuit is constructed at one end of the optical fibre as an electrically/optically converting transmitting device, and at the other end of the optical fibre as an optically/electrically converting receiving device. Exclusively electrical signals are switched via the plug-in connector. The plug-in connector is embodied as a multiple contact, and so apart from the signal line the power supply for the hybrid circuit located in the plug housing is also fed.
Patent DE-3805093-C1 (DE)
IPC: B65B35/30
Filed: 1988-02-18
Granted: 1989-03-09
Abstract: A method and an apparatus are described for making individual strips and feeding the strips to a packaging machine for the strips, in particular to a sealing machine, for sealing the strips into a sheet or foil. The individual strips are cut simultaneously from card-like material and by continuous constrained guiding led from the cutting means to the packaging machine. The constrained guiding is provided by magazines with receiving compartments for the strips and clocked transfer means. This makes it possible to obtain a high cutting output and a correspondingly high and exact packaging output. The invention is intended in particular for processing diagnostic test strips.

Title: Storage of radioactive waste casks in vertical boreholes - comprises stacking casks in hole, placing fine salt gravel around casks and using props or supports to limit hydrostatic pressure
IPC: G21F9/24
Filed: 1989-07-26
Granted: 1990-10-04
Abstract: Storage of radioactive waste in bore holes in  geologically safe salt formations uses drums immersed in fine salt aggregate.  Fine salt aggregate is layed in the bore hole before the first drum is placed and is put into the spaces around each drum as it is placed.  The result keeps each drum separated in a quasi hydrostatic suspension. After a predetermined number of drums a salt plug or divider is set in place.  This divider self locks in position by loading from above. ADVANTAGE - The drums do not have to be vertical or located accurately in the bore holes up to 600 m. deep.  No expensive equipment is involved and no point or line contact takes place.  More drums can be placed within a bore hole and the filler material specification is less demanding, (Previously notified in week 9045)

Title: Pressurised gas spring with cylinder - has annular groove in piston rod collar, whose depth permits retaining extra O=ring
IPC: F16F9/32
Filed: 1990-01-06
Granted: 1991-02-28
Abstract: The pneumatic spring cylinder (1) includes a cylindrical housing tube (2) which has both ends sealed by an insert (3, 4).

Patent DE-4002078-C1 (DE)
IPC: F02M35/024
Filed: 1990-01-25
Granted: 1991-05-02
Abstract: A filter element made of non-woven fabric formed as a folded package is self-supporting and is composed of thermally sealable non-woven fabric (1). Each of the two outer edges (3) of the folded package (2) is lined by the non-woven fabric material (1) forming the folds (4), which material, at each folded edge (3), is folded over in the same direction and is fixed to the corresponding bent edge of the adjacent end of fold in a tight fitting manner. The non-woven fabric material overlaps each bent edge of the adjacent end of fold by 1.5 to 2.5 times the fold separation. 
<??>To produce the filter element, the flat filter medium (1) is first folded and then a defined fold separation (7) is produced by a limited stretching perpendicular to the folding. The two outer edges (8) of the folded package are then positively clamped into comb-like sections (9) corresponding to the geometry and dimensions of the folds, and penetrating pincer-like into the folds on the upper and lower sides, the filter material projecting over the shaped sections (9) on each side by 1.5 to 2.5 times the fold separation (7). The overlapping material (10) is folded down on both sides in each case by means of a first pressing element (11) having a sideways action thereon, until the overlapping material (10) fits on the adjacent end of fold, so that the edges overlap. Energy allowing thermal sealing is supplied via these pressing elements (11). Further subsequent pressing elements (12) fix the sealed sites during cooling. The comb-like sections (9) are then removed and the folded package is contracted.

Title: Method for determining control parameters of an FM RF carrier
Inventor: GEYER PETER
IPC: H04B17/20
Filed: 1993-06-25
Granted: 1995-02-02
Abstract: In order to determine the control of an FM RF carrier the modulated RF carrier is first converted into a lower-frequency state (IF state). The period duration of each individual oscillation of the converted, modulated RF carrier, which corresponds to the frequency excursion of the frequency modulation, is counted. The time duration for each count increment is chosen to be essentially smaller than the period duration assigned to the IF frequency of the converted, modulated RF carrier. A separate frequency class is assigned to each count result, each count result increasing the frequency quantity in its assigned frequency class by the value "1". The frequency quantities of all classes are provided in reciprocal form and converted into linear correspondences. <IMAGE>

Granted: 1998-03-10
Abstract: FIELD: TV equipment. SUBSTANCE: method involves standard arrangement of information signals in sequence of lines of active information while each line has line gate start, for example, color video information signals. Then method involves shifting active video signal in time with respect to part of line synchronization of corresponding line by means of given slowly alternating time shift function, transmission of information about time shift to decoder by means of encoding instantaneous value of time shift signal for start of each field in region of beam reverse clearing in field sweeping of this field. Parts of trailing edge of active signal in previous line and parts of leading edge of active signal in current line are rejected in order to achieve reasonable region of time shift. During decoding method involves rejection of initial line gate signals and color synchronization signals and generation of new signals which are shifted in time with respect to active video signal by initial value which has been determined before encoding.
